Referring to the drawings in detail, Figures 1 to 3 inclusive show asash guide and cup structure, generally designated I 0, formed accordingto a preferred form of the machine and method of the invention, asconsisting generally of a sash guide II having a cup I2 secured in anaperture I3 therein. The sash guide II is employed in windows having asliding sash, and is secured to the window frame I4 by fasteners I3received in the cups I2, only one of which is shown. The sash guide I Iis roughly in the form of a channel member having a central groove Itfor slidably receiving the window sash, thegroove I6 being provided withside walls I! and a bottom wall I8, the latter, in turn, being providedwith recesses or countersunk portions IS surrounding the apertures l3(Figure 3). The countersinks or recesses I9 are provided for the purposeof receiving the edge flange 20 of the cup I2 so that the flange 20 willbe flush with the bottom wall I8 of the sash guide groove I6.

The cup I2 is of approximately cylindrical shape, and is provided withside walls 2! and a bottom wall 22, the latter having a hole 23 for thepassage of the shank of the fastener I5. The cups I 2 are preferablystamped out of sheet metal by means of dies, but may be formed in anyother manner.

The sash guide I I on the opposite sides of the guide groove I6 isprovided with front walls 23 and side walls 24. The latter terminate inbent portions 25 which engage the adjacent surface 28 of the windowframe I4. The fasteners I5 thus hold the portions 25 against the surface26 (Figure 3). The cups I2 serve to hold the heads of the fasteners I5below the level of the guide groove I6 so as to avoid any possibility ofinterference with the sliding of the sash in the sash guide II.

In order to secure the cup I2 in the aperture I3 of the sash guide II,the cup I2, after its insertion in the aperture I3, is provided withprotuberances or projections 21 (Figures 3, 4, 5) which are formed byforcing the material of the side walls 2| outward behind or beneath thebottom wall I3 of the guide groove l6. As the sash guide I I and cups l2are ordinarily made of metal this means and method of securing the twotogether is simple and effective.

In order to secure the cup I2 within the aperture l3 of the sash guideII (Figure 8) the assembly of the cup I2 and sash guide II is invertedand placed in a special forming fixture or machine, generally designated(Figures 8 and v9) with the bottom walls I8 of the guide groove I5resting upon the upper surface or anvil 3| of the machine 33. The latteris provided with a base 32 having a recess 33 therein closed by a coverplate 34 which carries the anvil surface 3|.- The cover plate 34 is alsoprovided with an aperture 35 of slightly smaller diameter than thediameter of the flange 23, so as to support the latter in the positionshown in Figures 8 and 9.

Reciprocably mounted in the recess 33 is a pair of oppositely-facingL-shaped plungers 36, the horizontal portions 31 of which are urgedtoward one another by coil spring 33 abutting th end walls 38 of therecess 33. A stop 40 mounted in a slot 4| midway between the end walls39 p1events the vertical portions 42 of the plungers 36 from touchingone another and leaves a gap 43 between them. The gap 43 flares outwardat its top (Figure 8) due to the fact that the inner edges of the topportions 42 are beveled oif as at 44 in opposite directions. Thevertical portions 42 are also provided with outwardly-facing roundedprojecting ends 45 which, during the operation of the machine 30, serveto form the projections or protuberances 21 which look the cups I2 inengagement with the sash guides I I.

In order to accomplish this, the machine '30 is mounted on the bed 46(Figure 8) of a press or similar machine (not shown) having avertically-reciprocating plunger 41 provided with a tapered lower end43. The plunger 41 i of a small enough diameter to pass through theopening 23 in the cup I2, and its tapered end 48 is inclined similarlyto the beveled portions 44 of the horizontally-moving plungers 33.

In the operation of the machine 30 and the process of this invention, acup I2 is inserted through one of the apertures I3 in the sash guide Iand the latter is then inverted (Figure 8) with the flange 2|! of thecup I2 resting on the rim of the aperture 35 in the cover plate '34 ofthe machine 30. The vertical portions 42 of the horizontally movingplungers 35 thus extend upward within the cup I2 and theiroutwardly-projecting ends 45 lie in a higher level than the countersunkportions I8 urrounding the apertures I3.

The press is then operated to cause the plunger 41 to move downwardthrough the hole 23 so that its tapered end 48 engages the beveledportions 44 of the vertical plunger arms 42 and forces them apart(Figure 9). When the rounded ends 45 engage the side walls 2| of the cupl2, they push these side walls 2| outward, forming the projections orprotuberances 21. While this is occurring, the rim of the aperture I3serves as an abutment to prevent the adjacent portion of the cup I2 frombeing likewise forced outward. The result is that the protuberances 21firmly lock the cup I2 to the sash guide II, with the countersunkportion I 8 firmly locked between the flange '23 and the projections orprotuberances 21. The Plunger 41 is then retracted upward (Figure 8),whereupon the coil springs 38 return the plungers 35 to their positionsin engagement with the stop 40, and permit the assembly Id of the cup I2and sash guide II to be withdrawn from the machine 30.

Since it is contemplated that the projections or protuberances 21 willbe formed in pairs at diametrically opposite positions in the side walls2| of the cups I2 (Figures 1, 3 and 4), the ends '45 of the verticalportions 42 of the plungers 36 are preferably bifurcated or in pairs inorder to produce two pro-tuberances 21 simultaneously side by side.

The modification shown in Figure 10 employs a cup 50 similar to the cupI2 used in the form of the invention shown in Figures 1 to 9 inclusive,but the sash guide 5| has an inwardly-extending cylindrical flange 52forming a cylindrical bore 53 in place of the aperture I3. The diametersof the bore 53 and the cup 50 are so chosen that it is necessary toemploy a considerable pressure to force the cup 50 into the bore 53 withthe cup flange 54 resting against the countersunk portion 55 of the sashguide 5|. This press fit of the cup 50 with the flange 52 of the sashguide 5| is preferably accomplished in aconventional pres (not shown) ofany suitable type. The cup 50 is thus held by frictional engagement withthe flanged portion 52 of the sash guide 5|.

The modification shown in Figure 11 is somewhat similar to that shown inFigures 1 to 9 inclusive in that the cup is held in engagement with thesash guide 6| by pushing the side walls 62 of the cup Iifloutward. Inplace of the projections 21, however, an annular projection 63 is formedon the opposite side of the countersunk portion 64 from the cup flange65. This may be accomplished by making the projections 45 of the machine30 (Figure 8) of semi-circular form so that the two halves in assemblyform a circular die, the halves of which are forced outward by theplunger 41, thu forming the annular projection 63. The operation offorming the annular projection 63 is otherwise similar to the operationof forming the projections 21 as previously described, hence requires noduplication of description.

In the modification shown in Figure 12, the cup 10 is united with thecountersunk portion 1| of the sash guide 12 by crimping the flange 13 ofthe cup 10 around the outwardly-flanged portion 14 surrounding theaperture 15 into which the cup 10 is inserted. In this modification(Figure 12), the crimping operation causes the outer portion 16 of theflange 15 to be turned outward parallel to the countersunk portion 1|,and the edge portion 11 of the cup flange 13 to be turned rearwardaround the edge of the outwardly-extending portion 13 and with its rimportion 18 turned inward around the same portion 16. The above-mentionedflange portions 13 and 14 are, therefore, interlocked with anoverlapping grip, this likewise being done in a crimping die (notshown).

What I claim is:

A process of securing a flanged fastener cup having a fastener hole inthe bottom thereof in a corresponding aperture in a sash guide, saidprocess comprising countersinking said sash guide around the margin ofsaid aperture, inserting said cup through said aperture with the flangeof said cup resting in the countersunk portion of said sash'guide,inverting the thus assembled cup and sash guide upon an abutment withthe cup flange and the surrounding sash guide surface resting againstsaid abutment and with the hole in the bottom of said cup exposed. andinserting a portion of an expander through said fastener hole in saidcup bottom and deforming the opposite portions of the side wall of saidcup outwardly on the opposite side of said sash guide from the sidethereof containing said countersunk portion and said cup flange, wherebyto lock said cup in said sash guide.
